Pennsylvania State Police said they did not make contact with Eric Frein, suspected of killing one state trooper and wounding another, overnight Saturday as the manhunt continued in a heavily-wooded swath near his parents' home.

With helicopters over head and law enforcement in camoflauge with K-9 units on the ground, Frein remained elusive Sunday morning while police remained vigilant.

"Our troopers are determined to find him and bring him to justice," Trooper Thomas Kelly said in a news release Sunday morning.

The "hot spot," according to dispatchers on Monroe County police radio Saturday, was on Blue Ridge Drive, which cuts through the densely wooded area and is about a quarter-mile south of the Frein home on Seneca Lane. The search has been focused on that area outside Canadensis since Friday night.

Frein is suspected of ambushing two state troopers outside their barracks in Blooming Grove, Pike County, on Sept. 12. Cpl. Bryon Dickson, 38, of Dunmore, Lackawanna County, died at the scene and Trooper Alex Douglass, 31, of Olyphant, Lackawanna County, was wounded and is recovering.

A day after shots were reported fired within a mile of the Barrett Township home Frein shares with his parents, police remained close-mouthed about why the gunshots reportedly heard at 7:15 p.m. Friday led them to believe Frein had returned to his neighborhood. But they were fairly confident he had been spotted.

"They wouldn't have brought all of us here if they weren't pretty sure he was in there, and pretty sure we could catch him," said a trooper at one of many roadblocks.

Among the morning arrivals Saturday was a state police tactical unit, specially trained for high-risk incidents. At 7:45 a.m., they pulled up in a small convoy of unmarked vehicles.

Another tactical team had worked through the night with scores of other troopers and local police, patrolling and checking one home after another in the wooded hills surrounding Frein's house. At one point, three helicopters and an airplane were circling the area straddling Barrett and Price townships. And K-9 units from New York joined those from Pennsylvania.

People living in Barrett and Price townships had been told to remain indoors and away from windows, with police issuing a "take-shelter warning" at 7:20 p.m. Friday. The order was lifted around 8:30 p.m. Saturday, leaving residents free to leave their homes. But that freedom was countered by a strongly worded caution: State police "are very concerned for the safety of the community and are strongly recommending that people in the affected area stay in their homes and do not go into the woods where law enforcement is searching," state police said in a news release.

Hours earlier, Kerriann Sanders was growing increasingly impatient in the home where she had intended to host her wedding that afternoon.

Sanders and Andrew Killinger had planned to get married in the backdrop of the scenic woods surrounding their Barrett Township home. But that plan was foiled when police locked down the neighborhood, keeping Killinger out and Sanders and their 2-year-old daughter, Riley, in.

"I was just nervous being home alone," said Sanders, as she was leaving the area — wedding dress in hand — under a police escort. The couple pushed the wedding back an hour and redirected the guests to an alternative site at a nearby restaurant.

Joe Ksiaskiewicz, who lives off Bear Town Road near Seneca Lane, was stuck at a roadblock after returning home from work at 5 a.m. Saturday.

He said police told him he couldn't cross into the neighborhood. "This is a critical time," he said a trooper told him.

One of his neighbors, he said, was allowed to leave the area to buy diapers for her baby but not permitted back in around 9 a.m.

In the meantime, residents were growing worried and bored as they tried to follow police orders. Ksiaskiewicz said his 27-year-old daughter, stuck at their house, was shopping online to pass the time.

Residents were told in state police press releases to check with media for updates but state police had no press briefings Saturday and none scheduled as midnight approached.

Troopers appeared to focus much of their effort on the woods but they also were looking closely at houses, ponds and brush as far as 2 miles away.

An hour after the gunshots were reported Friday night, police cars were in the area of Blue Ridge Drive and Bear Town Road in Barrett. On Friday, police were paying special attention to a house with a kicked-in screen door and to other homes that showed signs someone may have tried to force open any building.

At midnight, the Monroe County 911 Center van was packed up and driven away from its post at the Barrett Township building. A man in the van said the crew was done for the night, but he didn't know when the police would be finished.

In fact, police activity continued, and police vehicles were still coming and going at Route 447 and Bear Town Road on Saturday. It wasn't clear whether any police action was imminent.

Early Saturday, several residents of Bear Town Road were standing along Route 447 where it meets their street. The hum of car engines and whir of helicopters interrupted the usually tranquil setting, where deer tend not to leap across the road, but casually cross it.

Rich Barry said he was coming home from work in New York City around 7 p.m. when police stopped him at Route 447.

"I have a wife and a 2-year-old at home and I want to see them," he said. "I wanted to try walking back home, but an officer told me they'd put me under arrest."

At 3 a.m. Saturday, about 15 state police cars from the Montoursville and Towanda barracks crossed the roadblock at Route 447 and Bear Town Road and headed toward Blue Ridge Drive.

Hours earlier, on Friday, police radioed they were looking for a man who might be wet from crossing a body of water. Blue Ridge Drive winds around a large pond, created by a dam.

Thursday night state police searched the same Canadensis area for Frein, but found no sign of him.

State police have been hunting for Frein since Tuesday, when investigators identified him as their only suspect in the shootings.

He was linked to the ambush when police examined evidence from his parents' Jeep Cherokee, which a man walking his dog found Monday in a pond a few miles north of the Blooming Grove barracks.

Police believe Frein crashed into the pond because he was driving with his lights off and didn't notice he had reached a T-intersection at the north end of Route 402.

Police say Frein is a self-styled survivalist who has taken part in World War II and Cold War battle re-enactments, and who has expressed a hostility toward law enforcement officers. He is also considered a skilled marksman. He allegedly shot the troopers with a .308-caliber rifle.
